COPYING-BOOK.

SPECIFICATION forming part of Letters Patent No. 529,977, dated November 2'7, 1894.

Application filed October 3, 1893- Serial No. 487,108. (No model.)

- T0 at whom it may concern:

Be it known'that we, ALONZO B. TURNER and HUGH A. MCMULLEN, residents of Mount Savage, in the county of Allegany and State of Maryland, have invented certain new and useful Improvements in Copying-Books; and we do hereby declare the following to be a full, clear, and exact description of the inventlon, such as will enable others skilled in the art to which it pertains to make and use the same.

' The invention relates to books for filing letters or papers in proximity to copies of answers or of other papers to which they have some relation that renders it desirable that they be kept or filed together. It contemplates providing in a letter pressbook means for attaching original letters in proximity to copies of replies to the same in such manner that the two can be preserved and examined in close connection and in their natural order without covering any part of the face of the originals and also so that the originals shall form an opaque, back ground and also a support for the thin transparent sheets usually employed to receive letter press copies whereby the copies on such sheets are more easily read and whereby the sheets are kept from falling down and inwardly toward the back of the book and becoming doubled or folded therein.

The invention consists in the construction hereinafter described and particularly pointed out.

In the accompanying drawing the figure is an isometric view of the improved copying book.

Numeral 1 denotes the cover of a letter press copying book and 2 the usual leaves for indexing.

3 denotes the thin transparent sheets or leaves adapted to receive facsimile copies of replies to letters or of other papers, such as usually made by a press in well known manner. Between these leaves we interpose gummed strips 4 bound like the other leaves in the book. The gum or mucilage denoted by 5 is placed on one side only of the strip.

Its purpose is to provide for securing in the book original papers in close proximity to copies of other papers relating to them in their natural order. The adhesive, which may be of any approved kind, is placed on the right hand or last surface of the strip so that when the original paper has its outer back-edge surface pasted or gummed to said strip its written surface will face the answer or copy when the latter is in suitable position-to be read.

By gumming in the originals in the particular manner specified their unwritten backs are utilized as a background for the preceding copy made upon transparent paper. By this means the interference of the succeedingcopy with the legibility of its predecessor as experienced in ordinary letter press books is avoided and so also is the interference of the writing on the original since its written face is turned toward the succeeding page and awayfrom its predecessor which isto be read in the case assumed. Our arrangement also provides that the backs only of which are less likely to adhere to the gummed strips than the copying sheets. These'strips 6 are each interposed between the gummed side of a strip 4 and a sheet 3.

Originals made of ordinary opaque paper secured in place between the sheets of thin paper will not fall inwardly as readily as thin sheets but serve to hold the latter in place and. to prevent the united weight of such thin flexible sheets from folding and doubling between the covers.

Having thus fully describedour invention,

of said latter strips being on the side toward the end of the book and a calendered strip interposed between the adhesive surface of the gnmmed strip and the succeeding page, substantially as set forth whereby the gummed strip may receive the hack of the original and be arranged in natural order with respect to the answer and on an opposite adjacent page and the accidental sticking of strips avoided.

In testimony whereof we have signed this specification in the presence of two subscrib- 1o ing witnesses.
